Writing on Twitter, the Trainspotting writer said: "Bradley John Welsh, my heart is broken. Goodbye my amazing and beautiful friend. Thanks for making me a better person and helping me to see the world in a kinder and wiser way."

In Danny Dyer's Deadliest Men on Bravo in 2008, Bradley Welsh described himself as a "born leader".

In the programme he discussed his past as a Hibs Casual football hooligan in the 1980s.

He talked about how he "mobbed and robbed" and was involved with organised "smash and grabs" at stores, including Jenners in Edinburgh.

He later became involved in organising security at hundreds of clubs in Edinburgh.
